tftpd and pxe

I’m trying to boot a small linux system from a 6.3sp2 host using PXE/bootpd/tftpd. I’m currently trying to use pxelinux as the primary loader.

The bootp portion is working, pxelinux is loading and getting the necessary parameters but it reports that tftpd does not support the ‘tsize’ option.

The SP2 release notes indicate that this was fixed in tftpd but either I didn’t get the right one or it’s just broke.

I’ve seen references to pxegrub - any hints on where to get an x86 binary of this?

Suggestions? Alternatives?
